Title: Cloned superoxide dismutase
IPC: C12N/
Filed: 1986-10-29
Abstract: A double-stranded cDNA molecule which includes DNA encoding human manganese super oxide dismutase has been created. The sequence of one strand of a double- stranded DNA molecule which encodes human manganese superoxide dismutase has been discovered. Such mole- cules may be introduced in procaryotic, e.g., bacteri- al, or eukaryotic, e.g. , yeast or mammalian, cells and the resulting cells cultured or grown under suitable conditions sa as to produce human manganese superoxide dismutase or analogs thereof which may then be recov- ered. Human MnSOD or analogs thereof may be used to catalyze the reduction of superoxide radicals, reduce reperfusion injury, prolong the survival time of iso- lated organs, or treat inflammations. The invention also concerns a method of producing enzy- matically active human manganese superoxide dismutase or an analog thereof in a bacterial cell which contains and is capable of expressing a DNA sequence encoding the superoxide dismutase by maintaining the bacterial cell under suitable conditions and in a suitable pro- duction medium. The production medium is supplemented with an amount of Mn++ so that the concentration of Mn++ in the medium is greater than about 2 ppm. This invention also concerns a method of recovering purified enzymatically active manganese super oxide dismutase from bacterial cells.

Abstract: Fremgangsmåte for utvinning av uran fra våtprosessfosforsyre ved anvendelse av et alkylpyrofosforsyre-ekstraksjonsmiddel. Ekstraksjonsmidlet inneholder også et modifiseringsmiddel for under stripping å holde alkyl-pyrof osforsyreesteren oppløst i et fortynningsmiddel som er i det vesentlige ublandbart med vann. Efter at uranet er blitt ekstrahert fra våtprosessyren, behandles alkylpyrofosforsyreekstraksjonsmidlet med et oxydasjonsmiddel, som hydrogenperoxyd, og uranet blir overført til en alkalisk strippeoppløsning. Den alkaliske strippe-oppløsning er en vandig oppløsning av et alkalimetall-eller ammoniumcarbonat eller -hydroxyd. Det avmagrede ekstraksjonsmiddel resirkuleres for kontakt med fersk våtprosessyre. Eventuelt treverdig jern som er tilstede, blir utfelt i strippeopplsningen og derefter skilt fra oppløsningen. Uranet blir utvunnet, tørket og kalsinert til et UOg-produkt.

Abstract: Device for the washing of smoke gas, having an improved purifying action due to intensive application of foam. Specifically, the device consists of a radial compressor (10) connected to a smoke gas flue (18), said compressor, working in conjunction with a hood (24), forcing the smoke gas through purifying liquid (22) to which a foaming agent has been added, and through turbulence equipment (26), whereby foam is generated. Large amounts of foam may be generated, as excess is avoided by the action of a very efficient foam dispersal device (14). Said device consists of a radial fan (48) and deflection walls (52-58), against which the foam is projected. The walls are preferably conical in shape. The purifying liquid recouped during the dispersal stage is returned through return flow openings (64) to the foam generation area (12).

Abstract: In the paper coating operation a wet or dry edge from coating composition is formed on the, seen in the direction of movement of the paper web, downstream side of the doctor, the so-called stalagmite formation. This stalagmite formation leads to various problems in the papermaking process and especially occurs at high speeds of the paper web and/or a high solids content of the coating composition, which two operating conditions are exactly required to obtain a maximum paper yield and a high paper quality. According to the invention the stalagmite formation is effectively prevented by supplying a fluid inhibiting the stalagmite formation to an area bounded, on the one hand, by the paper web and, on the other hand, by the above side of the doctor blade. <IMAGE>
